excel mapping spreadsheet helper

Ive today re writen my old Honda tunning spreadsheet.
so it works with datalogit inputs.
 
basicly you tell it what target AFRs you are looking for, copy in your fuel correction table and then do a log of your AFRs in 3rd gear or which ever gear you prefer!
and then the last table works out the new fuel correction table etc.
obviously its a work in progress so use at own risk.
if anyone wants it mail me at merlin2002@ntlworld.com
 
Thanks

How would this work with rotaries with their 2 injectors per rotor?

[merlin2002]

All the spreadsheet does is work out the percentage difference between target afr and wideband afr log and works out a new table of corrections, how many Injectors rotors etc is not relevevt.
The main thing I changed was on the Mazda we have a fuel correction table on the fc so we can amend fueling there, on Hondas using crome you have to adjust the main fuel map.

sorry but that\'s old news.  This spreadsheet for Datalogit has been around for years. There is even a Yahoo group on it.

And yes  you need a good wideband AFR .

The sheet is a base you can work with but nothing really beats a good rotary tuner

used my honda version many times when I built a CRX Vtec Turbo etc
on PGMFI.org the honda forum it was new...that was like 3-4 years ago lol
